Non-technical Summary Geochronology uses multiple chemical, physical, and analytical approaches to estimate the ages of rocks, minerals, and organic materials over a wide range of geologic time. Geologists, archeologists, and other scientists use geochronology to study topics as diverse as the ages of the oldest rocks on earth (using radioactive decay of naturally occurring uranium into lead), the development of life on this planet, and our ancestors' mastery of fire and agriculture (using perhaps the most well-known method, Carbon 14 dating). The EarthScope Geochronology Graduate Student Training Program is a new initiative designed to promote interdisciplinary and innovative science by fostering new relationships between graduate students, scientists, and labs at different institutions, while simultaneously equipping the next generation of Earth scientists with an understanding of state-of-the-art geochronology tools that are profoundly important for conducting modern geoscience research. The program provides support to generate key, high-quality datasets for publications of mutual benefit to students, advisors, and labs; to found future research collaborations; and enable multidisciplinary science. The program is being launched by an EarthScope short course bringing together experts in the geochronology community for a series of lectures and discussions covering the fundamentals behind both the theory and practical uses of different geochronologic tools. At the end of the program, an EarthScope session convened at a national meeting and focused on North American continent evolution will synthesize the program?s results and allow evaluation of its overall success.Technical Description The basic structure of the program enables graduate students to apply for up to $10,000 to fund analytical costs, sample preparation, travel to the host lab, lodging, and other expenses for a project that advances some aspects of EarthScope science goals. These funds allow the students to visit the lab for a week or more, participate in the analysis and sample preparation, and learn fundamental aspects of the methods, techniques, and theory used in modern analytical facilities. Students can apply for funds to use whichever method is most appropriate for their proposed research project, including, but not limited to, U-Pb, Argon-40/Argon-39, Lu-Hf, Sm-Nd, Rb-Sr, U-series, fission-track, (U-Th)/He, Carbon-14, cosmogenic exposure, and luminescence dating. Any lab in the United States or its territories can participate. Laboratories wishing to participate in the program must simply provide a brief (1-2 page) written summary that describes the research and learning experiences a student should expect when visiting the lab. Students who are writing proposals are responsible for initiating contact with geochronology lab staff to discuss their project, timelines, and why this particular technique will help address the fundamental questions in their research proposal. If the lab director feels that this is a mutually beneficial opportunity, they provide a support letter and help the student refine and clarify their proposed research.This project is providing a number of potentially transformative outcomes, including the 1) fostering of new relationships and interdisciplinary, innovative science between researchers and labs at different institutions, 2) generation of new opportunities for students to gain hands-on experience with geochronology data acquisition and interpretation while being mentored by geochronology experts, 3) implementation of a low-cost mechanism for generation of key data for projects and publications of mutual benefit to students, advisors and labs, while laying the foundation for future proposals and collaborations, and 4) promotion of science that provides an important contribution to EarthScope's core science goal to investigate the geologic history of the North American continent.

非技术摘要的地年学使用多种化学，物理和分析方法来估计岩石，矿物质和有机材料的年龄在各种地质时期。 地质学家，考古学家和其他科学家使用地球文学学来研究地球上最古老的岩石（使用自然发生的铀的放射性衰变），这个星球上的生命发展，以及我们祖先的掌握火和农业的掌握（也许是最著名的方法，碳14阶段）。 Earthscope地球人工学研究生培训计划是一项新的计划，旨在通过在不同机构的研究生，科学家和实验室之间建立新的关系，同时为下一代地球科学家提供对先进的现代地质学工具的理解，这些工具对实现现代地理研究非常重要。该计划提供了支持，以生成密钥，高质量的数据集，以便为学生，顾问和实验室提供相互利益的出版物；建立未来的研究合作；并启用多学科科学。该计划是由Earthscope短期课程启动的，将地球体学社区的专家汇集了一系列的讲座和讨论，涵盖了不同地球体学工具的理论和实际用途背后的基础知识。在该计划结束时，在全国会议上召集了一个地球学会，重点介绍了北美大陆的进化，将综合该计划的结果并允许评估其整体成功。技术说明该计划的基本结构使研究生最多可申请10,000美元，以申请10,000美元，以资助分析成本，样本准备，向主机实验室，寄养的进一步的发展方面的项目，以及其他方面的项目，该项目的某些方面以及其他方面的一定程度的项目。这些资金使学生可以访问实验室一周或更长时间，参与分析和样本准备，并学习现代分析设施中使用的方法，技术和理论的基本方面。学生可以申请资金以使用哪种方法最适合其拟议的研究项目，包括但不限于U-PB，Argon-40/Argon-39，Lu-HF，SM-ND，RB-SR，U系列，U-Series，fission-Track，（Uth）/He，He，He，Carbon-14，Carbon-14，宇宙式暴露和发光量。美国或其领土的任何实验室都可以参与。希望参加该计划的实验室必须简单地提供简短的（1-2页）书面摘要，该摘要描述了学生在访问实验室时应该期望的研究和学习经验。正在撰写建议的学生负责与地球体学实验室工作人员联系，讨论他们的项目，时间表，以及为什么这种特殊的技术将有助于解决其研究建议中的基本问题。 If the lab director feels that this is a mutually beneficial opportunity, they provide a support letter and help the student refine and clarify their proposed research.This project is providing a number of potentially transformative outcomes, including the 1) fostering of new relationships and interdisciplinary, innovative science between researchers and labs at different institutions, 2) generation of new opportunities for students to gain hands-on experience with geochronology data acquisition and interpretation while being mentored by地球人工学专家，3）实施低成本机制，以生成为学生，顾问和实验室提供相互利益的关键数据，同时为未来的建议和协作奠定了基础，以及4）促进科学的促进，该科学为Earthscope的核心科学目标提供了重要的贡献，以调查北美洲际洲的地理历史。
